It is probably running, but it might not be in use. Check your configuration
file if it is listening on the address you think it is listening on (by
default, only, and check your /etc/resolv.conf to see if it is
pointing at

Additionally, if you changed resolv.conf, but did not restart firefox, it
might not be aware of the change.

Finally, firefox contains its own cache and might simply not be performing
queries that could be cached.

To get accurate numbers, use 'rec_control get', see
http://doc.powerdns.com/recursor-stats.html for which items you can 'get'.

This may not work if your recursor is too old, unsure what 'edgy' ships.

You'll find instructions on how to dump the cache on or near the link I
mentioned above.

Additionally, try running the recursor with 'quiet=off' or even 'trace=on'
for abundant detail about what is happening.
